1) Power-up Reminder Wiper Function

When turning off and on the auto INT switch, the system drives the wiper motor through LOW 

relay regardless of communication with rain sensor.

1.

When turning the INT-AUTO switch from the "OFF" to "ON" position with the ignition switch in 

the "ON" mode, the LOW relay operates to drive the wiper motor for 1 cycle, regardless of the 

rain sensor communication.

After that, when turning the INT-AUTO switch from the "OFF" to "ON" position, the LOW relay 

operates to drive the wiper motor for 1 cycle only if data from the rain sensor indicates rain 

drops.

2. FUNCTIONS OF RAIN SENSING WIPER

08-6

2) Washer Coupled Wiper in Rain Sensing Mode

The washer coupled wiper is operated when receiving the washer switch input with the ignition 

switch "ON" and the auto INT switch "ON" in rain sensing mode. At this moment, the 

communication with the rain sensor is overridden. However, a washer input is overridden if there 

is an output for continuous operation.

The operation data is sent to the rain sensor even during the washer coupled wiper's operation.

3) Sensitivity Control

The wiper LOW relay is turned on and the wiper motor runs one cycle when the volume 
sensitivity is increased (ex: sensitivity 0 ⇒ 1) while the ignition switch and the INT switch is 

in the "ON" position, and the wiper motor is in "Parked" position). However, the wiper motor can 

be operated only when the rain sensor detects the "Rain Detected" signal.

1.

If the volume sensitivity is changed more than 1 stage within 2 seconds, the wiper motor runs only 

one cycle.

4) Auto Light Control

Only when the auto light switch is in "AUTO" position, it controls the tail lamp and headlamp by 

communicating with the rain sensor (while the ignition key is in "ON" position).

5) When Wiper Parking Signal is Abnormal

The wiper system continuously outputs the parking signal of current sensitivity when the parking 

terminal is grounded (while the ignition key is in "ON" position and the INT switch is in "ON" 

position).

1.

When the parking terminal is fixed to IGN, the wiper system outputs the wiper operating signal for 

2 seconds, then continuously outputs the wiper parking signal.

※ The wiper motor runs only when the rain sensor requires the wiper operation.
